The climate of Prague, the Czech capital, is moderately continental, with cold winters, in which the temperature is often below freezing (0 °C or 32 °F), and mild or pleasantly warm summers.

Precipitation is not abundant, given that it totals 530 millimeters (21 inches), but it is well distributed over the months, with a maximum between the second part of spring and summer, and a minimum in winter, when it usually occurs in the form of snow or sleet.

Winter, from December to February, is cold: the average temperature is slightly below freezing. Due to stagnation of cold air in the lowest layers, there are many gray days, with snow typically light but quite frequent. On the other hand, cold air masses of Siberian origin can lead to intense frosts, in which the temperature can plunge below -20 °C (-4 °F).

Currency

The official currency of the Czech Republic is the Czech crown (koruna), abbreviated as Kč, with the international abbreviation CZK. 1 crown consists of 100 hellers (haléř), abbreviated as hal. Heller coins have not been in use as of September 1, 2008, but hellers are still incorporated into merchandise prices. The final price is always rounded off to the nearest crown value.
The approximate value of 100 CZK is approximately 4 EUR/5 USD.
Coins: 1 Kč, 2 Kč, 5 Kč, 10 Kč, 20 Kč, 50 Kč
Banknotes: 100 Kč, 200 Kč, 500 Kč, 1000 Kč, 2000 Kč, 5000 Kč

Currencies Accepted
As the official currency, the Czech crown is the best and often the only possible currency to use when paying. Although the Czech Republic is part of the European Union, the euro is not widely accepted here. Some stores, restaurants and hotels accept payments in euros but the exchange rate may not be very good.

Electricity

Electricity in the Czech Republic is 220V and AC 50Hz. Make sure your appliances like shavers, hairdryers, camera chargers, laptops, etc. have a switch to change the voltage to 220. All sockets have two round female contacts (live left) and round blanking/grounding protecting pin in the middle of the top. If you don’t have an adapter you can often purchase one at the airport when you arrive (plugs and adapters are hard to find in Prague shops, so be prepared and buy it at the airport or before you arrive). If you are visiting from North America you will need a transformer as North America works on 110V and 50 cycles and Europe works on 220V.
